Dirac fermion spectrum of the fractional quantum Hall states
Condensed Matter Physics, 2023 Applying a unified approach, we study the integer quantum Hall effect (IQHE) and fractional quantum Hall effect (FQHE) in the Hofstadter model with short range interactions between fermions.

Dephasing effect promotes the appearance of quantized Hall plateaus
New Journal of Physics, 2023 The quantum Hall effect (QHE) is a topologically protected phenomenon which has been observed in various systems. In experiments, the size of Hall bar device to realize the QHE is generally much larger than the phase coherence length, in which the ...

Quantum Spin Hall Effect [PDF]
Physical Review Letters, 2006 The quantum Hall liquid is a novel state of matter with profound emergent properties such as fractional charge and statistics. Existence of the quantum Hall effect requires breaking of the time reversal symmetry caused by an external magnetic field. In this work, we predict a quantized spin Hall effect in the absence of any magnetic field, where the ...

Quantum skyrmion Hall effect in f-electron systems
Physical Review Research, 2023 The flow of electric current through a two-dimensional material in a magnetic field gives rise to the family of Hall effects. The quantum versions of these effects accommodate robust electronic edge channels and fractional charges.

Quantum theory of the nonlinear Hall effect
Nature Communications, 2021 The nonlinear Hall effect is a quantum phenomenon, in which two perpendicular currents induce a Hall voltage; however, previous theories for this effect has remained at the semi classical level.

Quantum Hall effect originated from helical edge states in Cd_{3}As_{2}
Physical Review Research, 2021 The recent experimental observations of the quantum Hall effect in three-dimensional (3D) topological semimetals have attracted great attention, but there are still debates on its origin.

Ferromagnetic-electrodes-induced Hall effect in topological Dirac semimetals
Physical Review Research, 2021 We propose an unconventional type of Hall effect in a topological Dirac semimetal with ferromagnetic electrodes. The topological Dirac semimetal itself has time-reversal symmetry, whereas attached ferromagnetic electrodes break it, causing the large Hall
